Title: Delayed phasing address generator
Inventor: ISHIYAMA TOSHIO
IPC: G01S3/82
Filed: 1990-03-02
Abstract: PURPOSE:To make it unnecessary to consiously manage sampling addresses and to simplify control by providing the delayed phasing address generator with a sampling address counter for executing ring counting operation to always generate the newest sampling address. CONSTITUTION:The sampling address counter 1 counts up '1' in each input of a control signal CK1, and at the time of counting up a maximum value, returns its count value to '0' to continue count up operation again so as to generate always the newest sampling address(SA). A subtractor 2 subtracts a delay value address(DA) inputted from the external synchronously with a control signal CK2 and corresponding to a delay value set up in each channel from the SA and outputs the subtracted result. An AND circuit 4 masks bits larger than the maximum dealy value address out of addresses outputted from the subtractor 2 based upon a maximum address masking signal MMD outputted from a mask register 12 and generates a delayed memory address(DMA) updated like a ring within the maximum delay value address. Consequently, the management of sampling addresses can be made unnecessary and control can be simplified.

A pitch is so set that a gap 44 is provided between the bubble row 41 and a next signal track 43 generated by one rotation of the magnetic disc. Consequently, the original magnetization row which is directed upward remains in the gap 44 between signal tracks as it is. In case of reproducing, the beam 39 is irradiated to the signal row 41, and beams 40 and 45 are irradiated to tracks 42 and 44, their reflected lights are detected as a change of the intensity of light after passing a polarizing plate.
